Project 14
Clear Screen, More Arrays and Nested Loops (100 points)
 Allow the user to enter "n" many floats at the keyboard.
 Your Program must have a nested loop. The outter postest loop will allow
a new statistical report while the inner posttest loop will allow the input
of floats.

Using Standard Deviation Calculation Number : 1 as an example, your
array must be filled in the following manner :
num[0] = 4, num[1] = 2, num[2] = 3
Using Standard Deviation Calculation Number : 2 as an example, your
array must be filled in this manner :
num[0] = 245.6, num[1] = 14, num[2] = 1000.3, num[3] = 55
Using Standard Deviation Calculation Number : 3 as an example, your
array must be filled in this manner :
num[0] = 25, num[1] = 25, num[2] = 25
 For each set of data, you must calculate and output the :
 data
 frequency (How many)
 sum of the squares
 mean of the squares
 square of the mean
 variance
 standard deviation
The variance is defined as :
variance = (mean of the squares)  (square of the mean)
The standard deviation is defined as :
standard deviation = square root of the variance
 After each statistical report, make sure you clear the
screen. You can clear the screen by placing system("CLS")
in your program and by using the stdlib.h header file.
 Make sure your program can display the sample output below.
 Your code must be well documented. Also include your name, date,
project number and a breif description of the program.
